Final Draft: Slater vs Turkle How can Turkle’s concept of “authenticity” help us see Slater in a new way? Both face-to-face interaction and social networking sites (including Myspace‚ Twitter‚ and Facebook) are forms of staying in contact with friends and family. While Nora from Turkle’s “Alone together” communicates her engagement and wedding date via email to her closest friends and family‚ she could have easily announced it face-to-face‚ at a party or through a Facebook event.

that people are able to get DBS‚ deep brain stimulation‚ which is a surgery that implants a medical device‚ to improve their brain and to help them live a better life. But after the surgery does the person become more or less authentic? In Lauren Slater’s essay “Who Holds the Clicker?”‚ Slater studies the symptoms and experience of thirty-six years old Mario Della Grotta‚ who is diagnosed with obsessive – compulsive disorder‚ or OCD. He suffers from a live of looped-loop in which he repeats actions

two species competing for the same resources cannot coexist if other ecological factors are the same. When one species has even the slightest advantage or edge over another‚ then the one with the advantage will dominate in the long term. One of the two competitors will always overcome the other‚ leading to either the extinction of this competitor or an evolutionary or behavioral shift towards a different ecological niche. An example could be of squirrels in England. The Red Squirrel is native

developed by Ernst Haeckel in 1900s - The study of the interactions of organisms with one another and with their environment - not “the ecology” (wouldn’t say protect “the physics”) - not Environmental Science – study of how natural world works Ecological Systems Nested hierarchy - lowest level: look at individual organisms - biosphere highest level - organism most fundamental unit of ecology - organisms interact with the environment that is outside the individual‚ therefore is lowest level

Evolution Test Notes Giulia Palazzo • THE HARDY- WEINBERG PRINCIPLE: - a mathematical equation created to predict genotype and phenotype frequencies in a population that is not experiencing any selective pressure‚ if model fails evolution must be occurring - Under Mendel’s model‚ the two alleles can be represented by... p + q = 1 (100% of the alleles in the population) where p is the dominant allele and q is the recessive allele - The genotypes can be represented by the equation (p+q)² = p² + 2pq
